PILOTS:

Attention should always be paid to oil pressure coming up at every start within 15 to 20 seconds. If you do not have a positive indication (at least a needle flicker) in 15 - 20 seconds, you must abort the start. Do not attempt another start until the problem is corrected. Contact Customer Service at RAM Aircraft for assistance.

AIRCRAFT MECHANICS:

After an engine installation, oil pressure must be established on the engine prior to initial start. See our pre-oiling / priming instructions.

OIL PRESSURE ANOMALIES:

All aircraft piston engines are subject to oil pressure anomalies, primarily due to a loss of prime that normally occurs after one of these: 
( Engines are especially vulnerable immediately after installation. )

• Engine Installation

• After Periods of Inactivity

• After an Oil change

• After Major Weather / Ambient Temperature Changes

INSTALLING AN ENGINE - AVOID INTERNAL DAMAGE:

• Attention must be paid to oil pressure anomalies. If not, internal damage and ultimate failure will occur.

• Pre-oiling with a pressure pot is recommended. With spark plugs removed, turning the engine through with the starter is an acceptable method, but use extreme caution around the moving propeller.

• Note: Bleeding the oil line from the engine to the oil pressure gauge at the fitting will help the gauge show real-time pressure much quicker. While running the engine, have an assistant catch the residual oil in a cup at the gauge end. Dispose of properly.
